LEATHER-CUTTING TOOL.

To all whom it may concern Be it known that 1, Aims W. LARSON, a citizen of the United States, residing at Rockford, in the county of 'WVinnebago and State of Illinois, have invented certain new and usefullmprovementsin Leather-Gutting Tools, of which the following is a specification. I

This invention relates to cutting-tools and to those adapted for cutting leather or other material of similar quality and considerable body thickness and rigidity as contrasted with tools for cutting relatively thin fabrics, oil-cloth, ordinary paper, etc.

More particularly, a tool embodying my for cutting belts such as are used on drive pulleys in connection with machinery.

One of the primary objects of my invention is to provide a cutting-tool of simple design for cutting belts crosswise, easily and accurately, in order that the ends of the belts may be accurately joined to fit the belt to the pulleys over which it is to run.

I also aim to provide a cutting tool of this characterwhich shall be easy to handle and operate and shall consist of. but few parts, and which may be manufactured at a low cost.

' Another object of my invention is to provide in a cutting tool in which an edge of the material to be cut rests against'a sideguide, a cutter movable transversely of the side-guide and toward the same to cut the material cross-wise, and wherein the cutter maybe adjusted to cut in a path parallel with the side-guide.

Another object of my invention is to provide a combination cutting-tool wherein the cutter is slidable upon the tool to cut crosswise of the material and may be held fixedly on the tool whereby the tool may be operated as a cutting-gage to cut lengthwise of the tool.

Referring to the drawings: Figure 1 is a view in perspective of my improved cutting-tool showing the cutter as it is used when cutting cross-wise of the material. Fig. 2 is a View in perspective similar to Fig. 1, but with the cutter adjusted to a position whereby the tool may be used as a cutting-gage; and Fig. 3 is a view in perspective of the cutter-block and its connected parts in disassembled position.

It will be seen from an inspection of Fig.

"1 that the body of the cutting-tool very closely Specification of Letters Patent.

resembles an'ordinary try-square, the arm members of the body being designated by the reference characters t and 5. The member 5 is adapted to receive'on its top face the flat side of a belt or other material, and the member 4 is provided with a side-guideface 6 arranged at right angles to the member 5 and extending above the top face thereof,

whereby an edge ofthe belt lying on the member 5 may rest against the side-guide 6 and beproperly positioned with respectto said member 5.- The alsorests on a face 7 provided with teeth inclined toward the member 5. By holding the tool in the left hand with the thumb on topand bearing down upon the belt to hold the same firmly in connection with the Wrong.

Patented Apr. 6,1915. Application filed. September 29, 1914. SeriaI No. 864,128. V v if belt or other materialtoothed face, the belt will be securely held v in position on the tool, and the other hand of the operative may be used to. operate the cutting means which will now be described.

The member 5 is provided with a slot 8 formed T-shaped in cross section and extending length-wise of said member at right angles to the side-guide 6 and beyond'the side-guide as at 9. The slot 8 serves as a guideway in which is shaped cutter-block 11 which is square in horizontal cross-section. The cutter-block carries an upstanding cutting blade 12'ar'-- ranged to cut in a path parallel with one of the sides of the block.

ranged in Fig. l'the blade is facing the sideguide 6 so that when moving toward the said side-guide the blade will cut in a path at right angles thereto. The cutter-block carries a depending screw 13 upon whicha nut 14 is screwed to hold the cutter-block opera tively in the guideway and also to lock the cutter-block fixedly in connection with the guideway for a purpose as will afterward appear.

formed at its outer end with a handle 18; It is' obvious that with a strip of belting placed upon the tool and the tool held mone' slidably mounted a As the block is ar- A rod 15 extending through an ap'- erture 16 in the member 5 at one end of the slot 8 is screw-threaded at its end 17in connection with the cutter-block 11, and is thereby draw the leather ming the butt-edge of the belt and a relatively thin body of material may be out from the belt very accurately and quickly.

To use the tool as a cutting-gage the rod 15 would be unscrewed from the block 11 and detached from the tool, as also would the nut 14,-. The cutter-block could then be Withdrawn from the slot 8, turned a'quarterturn to position the blade parallel with the side-guide 6 as shown in Fig. 2, and be replaced in the slot at any desirable distance from the side-guide and locked fixedly in such position by screwing the nut 14 tightly against the underside of the member 5. The member l of the tool may then be grasped by one hand and with a belt or other material resting upon the members 5 and 7 and against the side-guide 6, the tool may be moved lengthwise of the material to cut in a path parallel with the guiding edge thereof. It will be observed that since the teeth on the member 7 are inclined toward the member 5 they will not interfere with the material when the cutter is moved in the direction opposite to that of the inclination of the teeth.

While I have shown and described a particular embodiment of the invention, 1 do 7 not desire to limit myself to the particular shaped slot extending embodiment shown, since various changes in the structural details may be resorted to without departing from the spirit of the invention or sacrificing any of its material advantages.

I claim:

1. In a cutting-tool of the character described, the combination of a body provided with a side-guide and having a T- transversely thereto, a block having a square portion and an enlarged head extending beyond the sides of said square portion, the block being slidably fitted in the slot whereby the block may be moved lengthwise of the slot, the block having an upstanding cutting-blade fixedly attached thereto, facing toward the said sideguide and arranged in a plane parallel with one of the sides of the block, whereby upon sliding the block in the slot toward the side guide the blade will out in a plane transverse to said side-guide, and means for holding the block slidably operative in the slot and for permitting the block to be removed I from the slot and replaced therein with its cutting-blade faced parallel with the sideguide.

2. A cutting tool comprising a body having a guide against which the edge of mate- IlELl to be cut abuts, a slot in the body extending transversely to said guide and being T-shaped cross-sectionally, a T-shaped cutter block mounted to slide in the slot toward and away from said guide, the cutter block being provided with an integral upstanding cutting-blade arranged in a plane parallel with the slot, whereby to cut in a plane transversely to said guide, a screw-member disposed beneath the slot overreaching the edges thereof and being in threadedconnection with the cutter block whereby to hold the same operatively mounted in the slot, and means for reciprocating said cutter block in the slot, the cutter block being removable from the slot, by removing said screw-member.
